Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on day one (04 Feb), quiet to minor storm levels on day two (05 Feb) and active to minor storm levels on day three (06 Feb). Protons have a chance of crossing threshold on days one, two, and three (04 Feb, 05 Feb, 06 Feb). MP: Replan command loads out for review. Due later today. ENG: Running Pre-Approved CAPs for CPE memory dump. GOT: No issues.
